Hi Blairtab,
Welcome to the forum! Pie charts are very easy to set up. First, make sure your data is set up accordingly. A simple pie chart should contain data that has two key elements - a data label and a data value that can be calculated. In the example below, I have a made up bill summary that contains the type of cost (Rent, Utilities, etc.) and their associated costs. Simply highlight the range that your data spans, then go to the Insert Ribbon, then find the Charts Pane near the center of the ribbon, select the pie chart graphic, and choose the style you like.
